TYPEWRITING MACHINE.

Application filed April 7, 1923. Serial No. 630,435.

chester and State of New York, have invented certain new and usefulImprovements in Typewriting Machines, of which the following is aspecification.

My, invention relates to carriage stop mechanism for typewritingmachinesand its chief object is to provide new and 1m-v proved mechanism of thecharacter specified. More specifically, one object is to construct,mount and control the stop devices that determine the margin of the worksheets so as greatly to facilitate varying the margin,

enabling indenting and paragraphing to be accomplished more quickly andeasily than heretofore.

To the above and other ends which will hereinafter appear my inventionconsists in the features of construction, combinations of devices andarrangements of parts hereinafter described and particularly pointed outin the claims.

My invention will be described in detail in connection with theaccompanying drawings wherein Figure 1 is a fragmentary front-to-rearvertical sectional view showing theupper part of a typewriting machineembodying my invention, parts of the machine not necessary to a fullunderstandmg of the invention being omitted.

Figure 1' is a fragmentary front elevation of parts shown in Fig. 1.

Figure 2 is a fragmentary rear elevation of the upper part of the saidmachine.

Fi re 3 is a fragmentary plan view showingt emargin stop devices, theirmounting and the stop controlling devices.

Figure 4 is a fragmentary front elevation \of the stop devices relatedas in Fig. 3.

Figures 5 and 6 are views corresponding to Fig. 4 but showing differentrelation ships of the stops.

Figure 7 is a plan view on an enlarged scale of certain of the stopdevices detached.

Figures 8 and 9 are vertical sectional views taken respectively on thesection lines l -l. and 2-2 in Fig. 7 and looking in the direction ofthe arrows at said lines.

' Figures 10 and 11 are enlarged perspective views of details.

rated side Referring first to Figs. 1, 2 and 3, the main frame of themachine comprises erfolates or frames 1 whic terminate at t e front andrear in inwardly bent flanges 2 and 3. The side frames are connected atthe rear and front b cross members not herein shown. Secured to the topsof the side frames 1 at the rear of the machine is an angular bed plate4 having a vertical portion and a horizontal portion, the horizontalportion being extended to provide a grooved trackwayor rail 5. Securedto the vertical portion of the bed plate is a grooved bar or trackway 6.The trackways 5 and 6 co-operate through anti-friction rollers 7 with atraveling platen care riage, said carriage comprising an inclined rearplate composed of parallel grooved barlike portions 8 and 9 which areconnected by cross webs l0. Extending forward from the plate 8-10 at itsends are end bars 11 which rotatively support a cylindrical-platen 12with the front face of which the type bars (not shown) are adaptedtoco-operate.

Carriage stop devices heretofore provided 7 for limiting the to-and-fromovements of the above described traveling platen carriage are fullydisclosed in a patent to Barr and Barney #1,447,689 granted March 6,1923. Said carriage stop devices comprise a. stop bar 13 having anarrower'toothed bar 14 secured to its under face. The end portions ofthe rack bar 13, 14 are fixed to rearwardly extending arms 15 providedwith eyes 16 which bear on pivot pins 17 extending lat-- erally outwardfrom ears 18 integral with the track bar 6. said pivot pins beingadjustably secured to said ears by set screws 19, the constructionproviding a pivotal. mounting for the rack or stop bar 13, 14, said barnormally being supported from the stationary track bar 6 but beingadapted to be swung up away from the bar 6. Adjustably mounted-on thebar 13, 14 are a plurality of stop or contact devices, four of suchdevices being shown and numbered 21, 22, 23, 24. These devices are alikein construction as to their body portions but differ as to their bar 13where it projects beyond thefront and back edges of the rack 14. Thefront bar and reset. The. top of the bar lip portion of each stop deviceis toothed as' indicated at 26 to correspond with the teeth of the rack14. Each stop device carries a wire spring 27 bent to a Z-shape andwhich is arranged under the top portion of the stop and has its endsco-operating with the sides of said top portion to prevent displacementof the spring. The spring 27 tends toexpand and constantly to maintainthe teeth 26 en aged with the teeth of the rack 14, thus fixing the stopin set position on its support. Downward pressure on the stop overcomesthe spring and disconnects the stop teeth from the rack bar, enablingthe stop to be adjusted lengthwise on said rack 13 is preferably formedwith a scale to facilitate-adjustment of the stop devices. The stopdevices 21 and 22 are arranged at the left-hand end portion and the stopdevices 23 and 24 at the right-hand end portion of the bar 13, 14. Thedevice 21 is provided with contact portions for operating the bellmechanism and line lock mechanism of the machine while the device 22constitutes the final line lock and endstop. The devices 23 and 24 atthe right constitute carriage arresting stops, usually calledrespectively the first and final margin stops. The member or device 23has a stop face 28 formed by the left-hand side of a lug 29 whichprojects forward at the front side of the device 23, the under side ofsaid lug being incline-d as indicated at 29 to provide a cam. The device24 is provided with a leftward extension 30 terminating in a-final stopface 31. (Jo-operative with the frame stop devices 21, 22, 23, 24, is acarriage carried contact or stop device 32 which is pivoted to the frontof the carriage bar 9 and has an upstanding lug or contact portion33. Inthe patented construction, when the carriage is returned from left toright to begin a new line, it will be arrested by contact of thecarriage stop lug 33 with the stop face 28 of the first margin stop 23,which determines the normal margin. In order that the carriage may bereturned further to the right, means are provided for moving the stopface 28 out of the path of the stop lug 33 so that the carriage may bemoved until arrested by the contact face 31 of the second margin stop24, thus changing the marginal point of arrest of the carriage. Thedisplacement of the stop face 28 to vary the margin is effected by keyactuated means which operates on the stop bar 13, 14. Said meanscomprise a plate 34 having a finger or extension 35 and secured byscrews 36 to the left-hand end portion of the stop bar 13, the free end.of said finger being adapted to be engaged by a cam device or slot 37formed in the upper arm of a lever 38 pivoted at 39 to the rear face ofthe bed plate 4. The

lower'arm of said lever 38 is also formed with a cam device or slot 40which co-opcrates with a pin 41 projecting rearward from the arm orplate 42 of an angular member which further .comprises a cross arm 43provided with pintles 44 having stationary bearings. The member 42, 43is constantly spring pressed downward and is adapted to be engaged bythe top of a vertically arranged push rod 45 which near its upper end isguided in a perforated stationary plate 46. The lower end of the pushrod 45 is pivotally connected to a key lever 47 having a stationarypivot 48 and which extends forward at the left-hand side of thekeyboard, being provided at its front end with a key or button 49. Onpressing said key, the lever 47 will be actuated to slide the rod 45upward in its guide, causing its upper end, which is contiguous to thearm 42, to swing the latter upward on its pivots in opposition to itsspring, lifting the pin 41. The upward movement of said pin will betransmitted through,the cam slot 40 to the lever 38, swinging said leveron its pivot, causing the cam 37 to push up- Ward against the finger 35,thereby swinging the stop bar 13, 14 on its pivots 17 from the normallower position as illustrated in Figs. 1, 35 to the lifted positionillustrated in Fig. 6. This movement of the stop bar carries with it allthe stop devices thereon and the stop face 28 will be raised out of thepath of the carriage stop 33, permitting the carriage to be movedtowards the right until arrested by the stop face 31, this stop facebeing so positioned that the lifting of the stop bar will not raise itfar enough to clear the path of the carriage contact or stop 33. Onreleasing the key 49 after the carriage has been thus arrested, theparts will drop back towards normal position, and as thereafter thecarriage is moved leftward, the cam or inclined edge 29" of the lug 29will be acted against by the carriage stop 33 lifting the stop 23 andthe stop bar 13, 14 slightly so as not to obstruct or prevent left--ward movement of the carriage. As soon as the lug 33 clears the cam face29*, it will permit the stop 23, the stop bar 13, 14 and the other stopsmounted thereon to drop back under the force of gravity to normalposition. It will be understood that the key 49 is also effective torelease the carriage after it has been arrested during its leftwardmovement by the stop 21 so as to enable additional characters to bewritten at the end of a line. As thus far described, the constructionand mode of operation of carriage stop mechanism corresponds with thedisclosures of the aforesaid Patent #1,447,639.

In the described construction as well as in other prior constructions,it is necessary to actuate the margin release key for every line whosemargin is to be changed, and whenever there was a considerable number ofsuccessive lines having the altered margin it has been common foroperators temporarily to re-set the margin stop, by hand,

changing it back to the first position when the normalmargin was to beresumed. In order to do away with this setting and resetting of marginstops or the alternative of actuating the margin release key for eachline of writing, I have provided new and improved mechanism whereby theactuation of a key is effective to alter the margin and change the.point of arrestof the carriage, the carriage being arrested in this newposition each time it is returned from left to right until the key againis actuated. this second actuation re-establishing the former margin andposition of arrest. To this end I provide a supplemental" carriagearresting or margin stop which preferably is connected to and adjustablewith the so-called first margin stop 23 along a common supportlengthwiseof the carriage, in the, present instance the supple mentalstop being movably mounted on said stop 28. The supplemental stoptogether with the stop 23 is shown detached in Figs; 7 9, saidsupplemental stop being designated as a whole by the numeral 50. Thebody of staid stop,5O isformed of a single 7 piece and comprises a crossport-ion or yoke which the arms 52 pass." The bottom edge 55 of each ofthese mouths is substantially horizontal and the corresponding upperedge 56 of the mouth is inclined upward toward the left, the two edges55 and 56 providing in effect a flaring opening or mouth affording alimited pivotal movement of the stop member 50 on the stop member 23.The

carriagearresting stop member or device 50 is provided with a projectionor lug 57 which is fixed to and projects forwardly from thefront arm 52,the lug 57 acting as an arresting stop proper in conjunction with thecarriage stop 33, the left-hand face 5801 said stop lug 57 acting as acontact face that co-operates' with the right-hand face of the stop lug33. The stop 50 will be adjusted lengthwise of its support 13 14 alongwith the stop 23, the teeth 26 of the latter co-operating with the teethof the rack 14 to maintain both stops 23 and 50 in setposition on theirsupport.

Means are provided for switching the carriage arresting stop 50 ormoving it up and down so as to render it operative andinoperative,without however altering its adjusted position on the stobar 13,14, said means being preferably ey actuated and comprising atrain of devices independent of the regular carriage arresting stops andtheir support 13, 14; Said train includes a pin 59 fixed to andprojecting rearwardly from the rear arm 52 of the stop 50 near itsleft-hand end, and overlying the bar 60 of a bail which is arrangedbehind the stop bar 13 and parallel therewith, the end portions or sidearms 61 and 62 of said bail being bent or off-set rearward from the bar60 and being pivotedon pins 63 which are secured in the pins 17 andproject inwardly therefrom towards the middle of the machine. Pivotallysuspended at 64 from the left-hand arm 61 is a rod 65,. the lower endportion of which passes through a hole in a stationary guide plate 66,said arm being adapted to slide up and down through said guide plate. Tomove said arm up and down and actuate the bail 60-62 there is providedan arm 67 shown detached in Fig. 10, said arm being provided with aperforated hub portion 68 and a bent-over lip or contact 69. The hub 68fits over the rear end ofa rock shaft 70 and is fixedly portions takehearings in the front flange 2 and'the rear flange 3 of the'left-handside plate 1. The crank arm 67 is mounted on the rock shaft forward ofthe flange 3 and may prevent rearward, displacement of the rock shaft.Just behind the front flange 2 there vis secured on the rock shaft 70 bya set screw 72 a collar or thimble 73 having at its front end adepression or seat indicated at 74 which houses a wire spring that iscoiled around the shaft 70 and is confined between the bottom of itsseat 74 and the rear face of the flange 2. The spring 75 tendsconstantly to expand and press the rock shaft 70 longitudinally rearwardin its bearings, normally maintaining the front rear edge of the switchor arm 76 seated in one or another of the depressions or notches 81 and82, thus locking the shaft 70 in one or another of two predeterminedpositions. The sides of the lug 83 are beveled or inclined to facilitatethe disengagement of the arm 76 and its swinging or switching movements.Sidewise pressure applied to said arm will cause it to co-operate withthe contiguous inclined side of the lug 83 which will act as a. cam toovercome the spring 75 and force the shaft 70 forward in its bearingsuntil the arm 76. disengaging from one notch, passes over the top of thelug 83 and will be forced down into engagement with the other notch bythe action of the spring 75, thus re-locking the shaft 70. The sides85of the ledge 80 project so far forward that they will always act aslimiting stops to prevent excess switching movements of the arm 76 evenshould the shaft 70 be drawn forward to the limit of its movement. Itwill be apparent that when the shaft 70 is rocked by the key 77 so as toswing the crank arm 67 upward, the contact'69 will engage with the lowerfree end of the rod 65 and will push the rod 65 upward through its guideplate 66, swinging the bail -62 upward on its pivots 63 and causing itto act against the pin 59 to swing or switch the stop device 50 upwardon its pivots. thus moving said stop from the Fig. 4 to the Fig. 5position, the latter being its inoperative position where its stop face58 is out of the path of the carriage stop 33. Conversely, a reverseturning movement of the shaft 70 will cause a lowering or swinging downof the crank arm 6769, permitting the bail bar 60 to fall and releasethe stop 50 which will return to the Fig. 4 position through the forceof gravity, its downward swing being limited by contact of the yoke orU-shaped cross portion 51 with the top of the stop bar 13.

The present form of my invention was particularly designed to facilitateindenting, as it is called, and the operation of the mechanism will bebriefly explained in connection with this character of typewritten work.Normally the parts may be assumed to be in the positions illustrated inFig. 5 wherein the stop device 50 is inoperative and the left-handmargin of the work sheet will be determined normally by the arrest ofthe carriage through the co-operation of the carriage carried stop 32,33 with the abutment 28 of the stop 23. When it is desired to writeoutside of the margin as thus determined, the key 49, as heretofore, isoperated to rock the stop bar 13, 14 and the stops thereon, includingthe stop 50, upward from the Fig. 5 to the Fig. 6 position, thusrendering the-stop 23 inoperative and permitting further rightwardmovement of the carriage until arrested by the stop face 31, as in Fig.6. On releasing the key 49 the stop bar 13 and the stop 50 together withthe other stops will return to the Fig. 5 position and the nextfollowing arrest of the carriage when moving rightward will be effectedby the stop face 28. The carriage arresting operations as thus fardescribed are the same as in the prior construction. When, however, itis desired to indent several successive lines or write inside the marginas determined by the arresting stop 23, the switch key 77 is pressedsidewise, unseating the arm 7 6 from the depression 82. said arm beingswung leftward and caused to engage in the seat 81, thus rocking theshaft 70 to swing the crank arm 67-69 down to the Fig. 2 position andreleasing the rod and the bail (v'()62, which the latter permits thestop 50 to drop down to the effective or operative position asillustrated in Figs. 1-1. The stop face 58 of the lug 57 is thus loweredacross the path of the carriage stop lug 33 so that on the next returnof the carriage from left to right it will be arrested by the contact ofthe lug 33 with the stop face 58 as in Fig. 4, at a predetermineddistance in advance of its normal position of arrest as determined bythe stop face 28. In the present instance the distance between the stopfaces or abutments 58 and 28 is equal to five letter spaces. the resultbeing that the next line of writing will be indented or set in fivespaces to the right of the normal margin on the work sheet, and thatthis indented margin will be continued as long as the stop face 58 isallowed to remain down in operative position. For a paragraph the stopface is kept down for a single line only. When the indented writing hasbeen completed. it is only necessary to actuate the key or finger piece77 as before described so as to rock the shaft 7 0 in the reversedirection to lift the crank arm 67-69 and cause the bail bar 60 to pressupward on the pin 59 and swing or switch the indenting stop 50 up to theinoperative position as in Fig. 5, said stop being locked up byco-operation between the arm 76 and the notch 82, which thus act asdetent devices for the said stop.

It will be seen that by my invention there is provided in combinationwith a traveling carriage and a carriage arresting stop, meanscontrolled by two separate keys for throwmg said arresting stop into andout of use,
